Description

Technical Field

[0001] This utility model relates to the technical field of duct bending devices, specifically a bending device for flame-retardant ducts. Background Technology

[0002] Flame-retardant air ducts are initially formed by bending horizontal flame-retardant material plates into a cylindrical shape. The flame-retardant material plates are bent using a bending machine.

[0003] According to Chinese Patent Publication No. CN220177905U, a bending machine with a duct fixing mechanism is disclosed. This machine places a steel plate on a support plate, and a motor drives a moving block to move left and right via a threaded rod. Then, an electric push rod is driven to extend or retract, clamping the steel plate through a clamping plate and a support seat, allowing the steel plate to move on the support plate. A pressing mechanism and a bending mechanism then bend the steel plate. One side of the bent steel plate rests on a limiting plate. After the next steel plate is conveyed by the conveying mechanism, the previously processed steel plate is pushed down, thus completing automatic loading and unloading, reducing labor and increasing operational safety. However, the bending device in this technical solution can only bend one duct material at a time, resulting in low efficiency and difficulty in meeting the needs of large-volume duct production, thus limiting its application. Therefore, we propose a bending device for flame-retardant ducts. Utility Model Content

[0004] The purpose of this invention is to provide a bending device for flame-retardant air ducts, which solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending device for a flame-retardant air duct, comprising a support platform, with a first leg and a second leg fixedly installed on both sides of the support platform, a bending mechanism installed on the outer side of each of the first and second legs, a pressing mechanism installed at the top of each of the first and second legs, a machine groove formed on the inner side of the second leg, a motor fixedly installed on the inner wall of the machine groove, a limiting groove formed on the support platform, a first fixed frame and a second fixed frame movably passing through the limiting groove, and a bidirectional screw fixedly installed at the output end of the motor. The rod has two fixed frames, one and two, threaded onto the outer wall of a bidirectional screw. Both fixed frames have short screws rotatably connected to their top ends via bearing seats. A Z-shaped push plate is fixedly fitted onto the outer wall of each short screw, with a slot at its bottom. The support platform has grooves near both sides, and a connecting shaft is rotatably connected to these grooves via bearing seats. A support roller is fixedly fitted onto the outer wall of the connecting shaft. An L-shaped pointer is fixedly installed on the front of both fixed frames, and a scale plate is fixedly installed on the front of the support platform near both sides.

[0006] Preferably, a limiting rod is fixedly installed at the top of both the first fixed frame and the second fixed frame. The limiting rod moves through the Z-shaped push plate. By setting the limiting rod, the first fixed frame and the second fixed frame can be limited, ensuring the stability of the Z-shaped push plate during use.

[0007] Preferably, there are several couplings, and the needle of the L-shaped pointer is set in front of the scale plate. By setting the L-shaped pointer and the scale plate, the personnel can more accurately grasp the bending position of the air duct material and ensure the bending production quality of the air duct.

[0008] Preferably, a knob is fixedly installed at the top of the short screw. By setting the knob, it is easy for personnel to rotate the short screw, thereby facilitating operation.

[0009] Preferably, both the first fixed frame and the second fixed frame are adapted to the limiting groove. By setting the limiting groove, the first fixed frame and the second fixed frame can be limited to ensure the stability of the first fixed frame and the second fixed frame when moving.

[0010] Preferably, both the first and second support legs have a retraction groove at their bottom ends. The top of the inner wall of the retraction groove is fixedly installed with electric cylinders one and two. The output ends of electric cylinders one and two are fixedly installed with support plates, and the bottom of the support plates are equipped with casters.

[0011] This utility model provides a bending device for flame-retardant air ducts. This bending device for flame-retardant air ducts has the following advantages:

[0012] (1) The bending device of the flame-retardant air duct can bend two flame-retardant air duct materials at the same time, which greatly improves the working efficiency of the device. By setting support rollers, the flame-retardant air duct material can be supported, and the friction between the material and the support table is greatly reduced, which improves the flexibility of the material when bending and moving. This solves the problem that the bending device in the existing technical solution can only bend one air duct material at a time, resulting in low working efficiency of the device, making it difficult to meet the production needs of a large number of air ducts, and having certain limitations in use. By setting L-shaped pointers and scale plates, personnel can more accurately grasp the bending position of the air duct material and ensure the bending production quality of the air duct.

[0013] (2) The bending device of the flame-retardant air duct can make the casters contact the ground and push the first and second legs off the ground. At this time, the personnel can directly push the device to move it, which greatly saves manpower and reduces the labor intensity of personnel when handling. The structure is simple and the practicality is strong. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1:

[0024] A preferred embodiment of the flame-retardant air duct bending device provided by this utility model is, for example... Figures 1 to 5 As shown: A bending device for a flame-retardant duct includes a support platform 1. Support legs 1 (2) and 2 (3) are fixedly installed on both sides of the support platform 1. Bending mechanisms 19 are installed on the outer sides of both support legs 1 (2) and 2 (3). Pressing mechanisms 18 are installed at the top of both support legs 1 (2) and 2 (3). A groove 4 is formed inside support leg 2 (3). A motor 5 is fixedly installed on the inner wall of the groove 4. A limiting groove 9 is formed on the support platform 1. Fixed frames 1 (7) and 2 (8) movably pass through the limiting groove 9. A bidirectional screw 6 is fixedly installed at the output end of the motor 5. Fixed frames 1 (7) and 2 (8) are... A threaded sleeve is fitted on the outer wall of the bidirectional screw 6. The top of the first fixed frame 7 and the second fixed frame 8 are rotatably connected to the short screw 11 through the bearing seat. The outer wall of the short screw 11 is fixedly fitted with a Z-shaped push plate 10. The bottom end of the Z-shaped push plate 10 is provided with a slot 14. The support platform 1 is provided with grooves 15 near both sides. The grooves 15 are rotatably connected to the connecting shaft 17 through the bearing seat. The outer wall of the connecting shaft 17 is fixedly fitted with a support roller 16. The front of the first fixed frame 7 and the second fixed frame 8 are fixedly installed with L-shaped pointers 20. The front of the support platform 1 is fixedly installed with scale plates 21 near both sides.

[0025] Specifically, in the above technical solution, when using the flame-retardant duct bending device, the material plates of two flame-retardant ducts can be placed simultaneously on the support platform 1, on opposite sides of the fixed frame 7 and the fixed frame 8, respectively. Then, the knobs 12 on the fixed frame 7 and the fixed frame 8 are rotated, causing the knobs 12 to drive the short screw 11 to rotate. The short screw 11 drives the Z-shaped push plate 10 to move downward, so that the two Z-shaped push plates 10 are respectively engaged with the two flame-retardant material plates through the slots 14. Then, the motor 5 can be started, causing the motor 5 to drive the bidirectional screw 6 to rotate. The bidirectional screw 6 drives the fixed frame 7 and the fixed frame 8 to move away from each other. The fixed frame 7 and the fixed frame 8, respectively, drive the two flame-retardant material plates to move downwards towards the pressing mechanism 18 on the support leg 2 and the support leg 3 through the Z-shaped push plate 10. The fixed frame drives the L-shaped pointer 20 to move on the scale plate 21. When personnel pass through the L-shaped pointer... When the flame-retardant material plate extends to the specified length from the support leg, as observed by the scale plate 20 and 21, the flame-retardant material plate is pressed and fixed by the pressing mechanism 18, and then the flame-retardant material plate is bent by the bending mechanism 19. Through the above structure, two flame-retardant duct materials can be bent at the same time, which greatly improves the working efficiency of the device. By setting the support roller 16, the flame-retardant duct material can be supported, and the friction between the material and the support table 1 is greatly reduced, which improves the flexibility of the material when bending and moving. This solves the problem that the bending device in the existing technical solution can only bend one duct material at a time, resulting in low working efficiency of the device and difficulty in meeting the production needs of a large number of ducts, which has certain limitations in use. By setting the L-shaped pointer 20 and scale plate 21, the personnel can more accurately grasp the bending position of the duct material and ensure the bending production quality of the duct.

[0026] Furthermore, a limit rod 13 is fixedly installed at the top of both the first fixed frame 7 and the second fixed frame 8, and the limit rod 13 moves through the Z-shaped push plate 10.

[0027] The limiting rod 13 can limit the movement of the first fixed frame 7 and the second fixed frame 8, ensuring the stability of the Z-shaped push plate 10 during use.

[0028] Furthermore, there are several couplings 17, and the tip of the L-shaped pointer 20 is positioned in front of the scale plate 21;

[0029] By setting an L-shaped pointer 20 and a scale plate 21, personnel can more accurately grasp the bending position of the duct material and ensure the bending production quality of the duct.

[0030] Furthermore, a knob 12 is fixedly installed at the top of the short screw 11;

[0031] The knob 12 is designed to facilitate operation by allowing personnel to rotate the short screw 11.

[0032] Furthermore, both the first fixing frame 7 and the second fixing frame 8 are adapted to the limiting groove 9;

[0033] By setting the limiting groove 9, the fixed frame 7 and the fixed frame 8 can be limited to ensure the stability of the fixed frame 7 and the fixed frame 8 when they move.

[0034] Example 2:

[0035] Based on Embodiment 1, a preferred embodiment of the flame-retardant duct bending device provided by this utility model is, for example... Figures 1 to 5 As shown: both support legs 1 2 and support legs 2 3 have a shrinkage groove 22 at their bottom ends. Electric cylinder 1 23 and electric cylinder 2 26 are fixedly installed on the top of the inner wall of the shrinkage groove 22. Support plate 24 is fixedly installed on the output end of electric cylinder 1 23 and electric cylinder 2 26. Universal wheel 25 is installed at the bottom end of support plate 24.

[0036] Specifically, in the above technical solution, when the entire device needs to be moved, the electric cylinder can be activated. The electric cylinder drives the support plate 24 to move downward, causing the support plate 24 to drive the caster wheel 25 downward, so that the caster wheel 25 contacts the ground and pushes the first support leg 2 and the second support leg 3 to leave the ground. At this time, personnel can directly push the device to move, which greatly saves manpower, reduces the labor intensity of personnel during handling, and has a simple structure and strong practicality.

[0037] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
